The Body’s Internal Clock and Cancer: How Cell Maturity May Be Involved

Circadian clock dysfunction may be linked to dedifferentiation and cancer development.

• The circadian clock regulates various physiological and behavioral processes aligned with Earth's 24-hour cycle.
• Most cells exhibit circadian patterns in gene expression, with the master regulator located in the hypothalamic suprachiasmatic nucleus.
• Embryonic stem cells and induced pluripotent stem cells do not demonstrate circadian oscillations until they differentiate.
• The emergence of the circadian clock during development is closely tied to cellular differentiation.
• Certain cancer cell types also lack a functional circadian clock, suggesting a potential connection to cancer biology.
• Circadian rhythm abnormalities may be associated with various diseases, including cancer, highlighting the need for further research.
